What are asteroids made of?

Most of these asteroids feature large volumes of carbon molecules along with the harder usual rocks and metals.

The composition of an asteroid can be very similar to the carbonaceous chondrite meteorites that occasionally fall on this planet. It happens to be why these meteorites usually are chippings, smashed off in the course of collisions between asteroids.

On April 19, Asteroid 2014 JO25 to fly safely passing Earth, around 1,090,733 miles away from Earth, which roughly translates to 4.6 times the distance between the planet and the Moon.

At the same time on April 19, the comet PanSTARRS is going to make a flyby with its closest approach to Earth, in a very secure range of 109 million miles. A faint fuzzball in the sky when it was discovered in 2015 by the Pan-STARRS NEO survey group using a telescope over the summit of Haleakala, Hawaii.

The comet features brightened considerably due to a recent outburst as well as is now noticeable during the dawn sky with binoculars as well as a small telescope.

Asteroid 2014 JO25, about 2000 feet wide was discovered in May 2014 by astronomers at the Catalina Sky Survey near Tucson, Arizona-a project of NASA’s NEO Observations Program in a joint venture together with the University of Arizona.

Asteroid 2014 JO25 closest flyby in 400 years

Modern measurements by NASA’s NEOWISE mission point out that this asteroid is approximately 2,000 feet in dimensions. Its surface area is approximately 2 times as reflective as that of the moon. At this point hardly any else is known about the object’s physical properties, even though its trajectory is well known.

The asteroid will get close to Earth coming from the direction of the sun and can become visible in the night sky just after April 19.

It’s expected to brighten to about magnitude 11, when it may be visible in small optical telescopes for one or two nights before it fades given that the distance from Earth instantly heightens.

Right after analyzing the orbit of Asteroid 2014 JO25, astronomers aware the April 19 encounter could be the closest this asteroid has get to Earth for at the very least 400 years and will be its closest approach for at least the next 500 years. There is no danger as the space rock’s orbit is well known, report said. Image of “What are asteroids made of?” / NASA

How old is the earth according to Science?

We have been told by science that the earth was formed billion years ago. Based to radiometric dating and other sources of proof, Earth formed about 4.54 billion years ago.

Earth’s gravity interacts together with other objects in space, especially the Sun along with the Moon, Earth’s only natural satellite.

Throughout one orbit around the Sun, Earth rotates related to its axis over 365 times; therefore, an Earth year is about 365.26 days long. Earth’s axis of rotation is tilted, making seasonal variations on the planet’s surface.

The gravitational relationship between the Earth and Moon causes ocean tides, stabilizes the Earth’s alignment on its axis, and progressively slows its rotation.Throughout the first billion years of Earth’s history, life sprang out in the oceans and began to affect the Earth’s atmosphere and surface, leading to the proliferation of aerobic and anaerobic organisms.

A number of geological evidence indicates in which life may have arisen as much as 4.1 billion years ago. Given that the combination of Earth’s distance from the Sun, physical properties, and geological history have allowed life to evolve and thrive. In the history of the Earth, biodiversity has gone through extended cycles of expansion, from time to time highlighted by mass extinction occurrences.

Modern science holds that the Earth is an unbroken sequence of layers, crusts, and liquid magma surrounding a dense, hot core made primarily of iron and nickel. But not everyone is convinced.

Is the earth really hollow?

In the 17th century, some of the leading scientific minds of the time came up with a new theory-that the planet is actually hollow. This idea has turned out incredibly durable.

To this day, there are huge numbers of Hollow Earth believers who are dealing with valiantly to validate their particular ideas through books, online social media websites, conferences and some extremely driven travel plans.

An account of Olaf Jansen and his father Jens Jansen, Norwegian fishermen, accidentally discovered the North Polar Opening in 1829 in search of the “Chosen Ones” of their ancestors and entered the hollow earth in which they lived for two years with the giant people there. Olaf then returned to Sweden by way of the South Polar Opening after being recovered by a Scotland whaleboat from an iceberg. His father was wiped out when their fishing boat was knocked and sunk by the iceberg in Antarctica. Olaf later immigrated to the United States and died in Los Angeles in 1908.

The Hollow Earth theory and an expedition to the Arctic

The Hollow Earth idea states that the Earth is a hollow planet along with historic entrances to the subterranean world scattered throughout it, which includes near both polar caps.

This theory has been reported since ancient times and scientists such as Edmund Halley have defended it throughout history. Amid most believers, the interior of the Hollow Earth is a lush tropical paradise that very likely houses an advanced race of humans, aliens, giants. In most scenarios, the inhabitants are the descendants of historic races such as the Lemurians. according to modern theorists like Dallas Thompson.

The beings there dwell thousands of years, “protected from the harmful cosmic rays and other pollutants that exist on the surface.”

Generally, this new perspective of the hollow Earth is accompanied along with the theory of a small sun that hangs in the very center, creating a lush, livable environment on the flip side of the Earth’s surface.

According to a number of hollow Earth websites, this vision was formulated among famous mathematicians and scientists such as Leonhard Euler in the 18th century and Sir John Leslie in the 19th century, although the sources for these accreditations seem to be somewhat nebulous.

John Cleves Symmes, Jr declaration

Regardless of where it originated, the version of a Hollow Earth managed to grow and succeed. In 1818, John Cleves Symmes, Jr. published his Circular No. 1, declaring to the world that the Earth is hollow.

Symmes, a veteran of the War of 1812 and unsuccessful trader, soon became maybe the most famous and successful proponent of the Hollow Earth theory. His preliminary vision of the Earth’s interior had been like a simplified version of Halley’s multi-layered model. With the exception that Symmes’ version included huge holes at the North and South poles which allowed entry to the buried world inside.

These types of holes, his unique addition to Hollow Earth theory, would even consider to be known as “Symmes Holes.”

In his very first statement, Symmes proposed to mount an expedition to the North Pole, where he was sure they could locate one of these apertures, and gain entry to the inner Earth. He too believed that the interior of the Earth not only could, but did support life. Stating in Circular No. 1, that the inside of the Earth would be “stocked with thrifty vegetables and animals if not men.”

Symmes believed that his theory was not science tale fantasy, but science fact, and that it applied not only to the Earth, but too all planetary bodies. To him, the whole universe was hollow.

Admiral Richard E. Byrd first hand experience

In 1926, Admiral Richard E. Byrd and his pilot Floyd Bennett pursued a flight over the North Pole on May 9th. Based to Byrd and Bennet. The flight took 15 hours and 57 minutes from Svalbard, Norway, into the Arctic and the North Pole. They reported journeying 1,535 miles.

Admiral Byrd wasn’t the only person to claim he reached the inner earth, or to would suggest that the poles of the Earth have been open holes that served as entrances to Aghartha.

Admiral Byrd supposedly maintained a diary of his expedition over the North Pole in 1947. This diary notes Byrd’s journey into the center of the Earth.

He details a completely unique environment as he passed the Pole, citing enchanting green hills and temperatures of 74 degrees Fahrenheit. Directed to land by messages coming into his aircraft, Admiral Byrd explains that he and his pilot were approached by beings of inner Earth who also introduced them as “surface world men.”

The Scientific study and basis for Hollow Earth concept

Perhaps the earliest person to scientifically speculate related to a hollow earth was none other than Edmund Halley, of Halley’s Comet fame. Suggested in 1692 as a way of detailing anomalous compass measurements. Halley’s theory is that the planet is a sequence of nested, spherical shells, spinning in different directions. All surrounding a central core.

In his evaluation, primarily based on measurements of the magnetic field and what he knew of the gravitational pull of the sun and the moon on the Earth. This model could account for any inaccuracies in his readings of the magnetic fields of the planet. He also put forward that the space in between each shell may have had luminous atmospheres suitable of supporting life.

Edmund Halley (1656 – 1742), the English scientist who studied the comet that bears his name, may have been the first to develop a scientific hypothesis about the Hollow Earth. After a series of observations of the Earth’s magnetic field.

Halley agreed that the anomalies observed could only be revealed if the Earth was composed of two spheres. An external solid one and an internal hollow one, each with its own magnetic axis.

The main perception in the Earth having an enchanted center probably arose from the fact that the deeper one penetrates into the Earth, the warmer it gets. But it is a far-fetched assumption to suppose that this increase of temperature remains until the center of the Earth.

There is no evidence to support this view. It is more possible that the increase of temperature continues only until we reach the level where volcanic lava and earthquakes originate. Probably due to the existence of much radioactive substances there. But after we pass through this layer of maximum heat, there is no reason why it should not get cooler and cooler as we get nearer and nearer to the Earth’s center.

The entire surface of the Earth is 197 million square miles and its estimated weight is six sextillion tons. If the Earth was a solid sphere, its weight would be much greater.
